AW: Conversion to RPGLE & commitment control

Hi,

1. Commitment control will also work for RPGIII programs, you do not have to
convert them to RPGIV.
2. You have to create a Journal and Journal receivers and register your
physical files in this journal.
3. If you want to use Commitment control in your RPG-Programs, you have to
add the keyword COMMIT (COMIT)
   for you update and output files in the F-Specs.
4. You do not need to specify COMMIT for Input-Files.
5. You have to decide where to set COMMIT and ROLBK in your programs.
   A record remains locked until the next COMMIT or ROLBK.
   UNLOCK or Extender (N) will not free the record.
6. Because Journaling requires additional actions, performance may go down a
little
   and you'll need some additional disk space.
7. You have to start commitment control for your job STRCMTCTL.
   Be careful the default value for Commitment Scope is activation group.
   As long as you do not have a true ILE environment, commitment scope
should be set to *JOB.

I hope that helps, for more information look at the online library.

Betreff: Conversion to RPGLE & commitment control


In our application, we have a series of 9 RPG programs that creates all
transactions.  The problem is that there is little or no error checking for
such things as record lock.  We have nightly audit reports that verify
balances & every few months or so it finds a problem where not all of the
files were updated.

I am trying to make a case to put commitment control on this process.

Some of the issues are:
-       The RPG programs need to be converted to RPGLE so commit can span
all the programs.  Will a simple IBM conversion {no commit} change how the
program works?  Does IBM guarantee there is no difference?
-       Will the performance with commit suffer?
-       What is needed to add in commit to this process?
-       Some programs don't do any updates.  They just return info.  Do they
need to be converted to RPGLE?
-       Any others?


Since I work for a bank, the paranoia level is high.  The general feeling is
"If it ain't broke...don't fix it" and "Do you realize how much testing we
will have to do for this change?"
